Exchange Active Sync - "protocol version not supported"

[pgnitcheu]

I configured a Microsoft Exchange Active Sync account on my android device (Samsung galaxy S6). All is ok, except when i launch a search from my device i have the error message "protocol version not supported".
The zimbra version is community 8.6.0_GA_1162

Hello pgnitcheu,
welcome to the forums!

Samsung devices are limited by default to version 2.5 of the Exchange ActiveSync protocol to avoid protocol-compatibility issues found in almost all the Samsung roms since Android 4.0. You can change this in the ZxMobile section of the ZeXtras Administration Zimlet if there are no old Samsung devices connecting to the server, otherwise you can set up a dedicated rule for your account using the `doAddEASFilter` CLI command:

zxsuite mobile doAddEASFilter and account=user@example.com,contains=samsung fixed 14.1 blocking true

This will force any device preseting itself with a string containing "samsung" to synchronize your mailbox using version 14.1 of the EAS protocol. In order to take effect, you'll need to remove the Exchange account from your device and reset the device's syncstate by deleting the relevant line in the "Devices" list within the ZxMobile section of the ZeXtras Administration Zimlet.

Since this issue has never been reported before could you please let me know the Android version running on your device, the client used to sync the emails (default or third party) and confirm that you are running the latest version of ZeXtras Suite?

Have a nice day,
Cine

I can report that I have this problem with my S7. Thanks for the details on how to fix it. It was annoying not being able to search the server.

The search feature still isn't working. I'm thinking it is still trying to sync using 2.5. I checked sync.log

2016-06-30 12:48:00,916 INFO [ZxMobile] [tid=195642;account=me.address@mydomain.com;id=SEC2 40E753FD2FFF;model=SAMSUNGSMG930V;proxy=192.168.0. 245;oip=192.168.8.87;eas=2.5;rid=47032;] sync - Requested push notification for folders: ...

It says eas=2.5.

I checked the rule and my addition is below a rule specifying 2.5 for samsungs. I tried using the doMoveEASFilter and it gave me the following error. "exception: Unable to move a filter before a static filter"
Below is a dump of the filters that I have. 0-2 must be default because I never added any.

Hello Stephen!

Did you delete the account from the device and reset its syncstate by removing the appropriate entry in the "Devices" list within the ZeXtras Mobile section of the Admin Zimlet?

Cine,

That was what I missed. I cleared that and then reconnected and now it is syncing at EAS 14.1. Thank you.
